Pharmacology

Acetaminophen, a para-aminophenol analgesic, is the active metabolite of phenacetin. Although, Acetaminophen's analgesic and antipyretic activity is similar to aspirin, Acetaminophen has no peripheral anti-inflammatory activity or effects on platelet function. Acetaminophen is used to treat both acute and chronic pain, on its own or in combination with pseudoephedrine, dextromethorphan, chlorpheniramine, diphenhydramine, doxylamine, codeine, hydrocodone, or oxycodone.

Mechanism Of Action

Acetaminophen is thought to act primarily in the CNS, increasing the pain threshold by inhibiting both isoforms of cyclooxygenase, COX-1 and COX-2, enzymes involved in prostaglandin (PG) synthesis. Unlike NSAIDs, Acetaminophen does not inhibit cyclooxygenase in peripheral tissues and, thus, has no peripheral anti-inflammatory affects.

Toxicity

Acetaminophen, the parent compound, is nontoxic, but hepatic metabolism leads to formation of a toxic metabolite, N-acetyl-benzoquinoneimine (NAPQI). The liver metabolizes more than 90% of acetaminophen to glucuronide and sulfate conjugates, which are eliminated in the urine. In children, sulfation is the primary pathway until age 10-12 years; glucuronidation predominates in adolescents and adults. Only a small amount of acetaminophen (2%) is excreted unchanged by the kidney. Hepatotoxicity is the result of formation of the reactive and toxic metabolite NAPQI by the cytochrome P-450 system. A single ingestion of 7.5 g in an adult or more than 150 mg/kg in a child is a potentially toxic dose of APAP.
